Forecasters say some parts of Iowa may be in for rough weather this weekend, including thunderstorms, strong winds and heavy rain. Meteorologist Kevin Skow, at the National Weather Service, says it’s a good idea to keep an eye on the sky and an ear to the radio. “The best threat for severe weather looks to be on Saturday,” Skow says. “We have a warm front lifting north through the state and this could trigger some severe weather.” He says there’s a larger threat for severe weather to the southwest in Nebraska, Kansas and Oklahoma.
After a mild winter and the warmest March on record, Iowans have been spoiled by the unseasonable temperatures, but in the past week, reality has returned with Freeze Warnings three nights in a row. Skow says warmer temp are heading back to the state, but just for a few days. “Temperatures should rebound,” he says. “Winds will switch to the south. Temperatures on Saturday will be rising up into the low to mid-70s and then that’ll be the same for Sunday.” He expects a cold front to move in Sunday night that’ll bring chilly temperatures to start next week, with highs again in the 50s.

OMAHA, Neb. (AP) — The U.S. Army Corps of Engineers plans to release another report examining last year’s flooding along the Missouri River. The Corps will release a report Friday looking at how much free space it would have needed in reservoirs along the river to handle last year’s deluge of water. The report will also look at how other uses of the river, such as navigation and recreation, would have been affected by storing that much floodwater. A report from outside experts released in December said the corps did the best it could to deal with last year’s record flooding. Officials have said nearly all of the 16.3 million acre-feet of the planned storage space for floodwater is available in reservoirs along the Missouri River thanks to recent warm, dry weather.
